Andrey Panov released an update to Liberastika — a fork of free open souce Liberation font family that improves Cyrillic letters (and goes beyond that, actually).
There are not many changes, but you still might like them:
- U+04CF was replaced with reference to "l";
- U+1E9E (uppercase Я) was added;
- some TrueType instructions were fixed.
